APEM 5664MTHAB Toggle Switch DP3T Equivalent & Substitute Parts

Part Overview

The APEM 5664MTHAB is a panel-mount toggle switch with DP3T (double-pole triple-throw) circuit configuration, rated for 6A AC at 125V and 4A DC at 30V. This switch is designed for applications requiring three distinct switching positions with maintained contact. The part is currently active in production with 1051 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to availability constraints, supply chain considerations, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the APEM 5664MTHAB is determined by the following critical parameters:

Circuit and Function Compatibility: The substitute part must maintain DP3T circuit configuration with On-On-On switching function to preserve electrical behavior in the application.

Electrical Ratings: The substitute must meet or exceed the voltage and current requirements. The APEM 5664MTHAB operates at 6A AC/125V and 4A DC/30V. Substitute parts must support these or higher ratings to ensure safe operation.

Mechanical Interface: Panel-mount configuration, solder lug termination, and bushing thread specification (15/32-32) must be identical to ensure physical compatibility with existing panel cutouts and wiring harnesses.

Actuator Specifications: Standard round actuator type with actuator length within acceptable tolerance ensures consistent user interface and panel integration.

Environmental and Compliance Requirements: Operating temperature range, RoHS compliance status, and electrical life cycle rating must be suitable for the intended application environment.

The C&K 7411TZQE qualifies as a substitute based on matching circuit configuration (DP3T), switching function (On-On-On), mounting type (panel mount), termination style (solder lug), and bushing thread specification. Electrical ratings are comparable with 5A AC/120V and 4A DC/28V, representing a minor reduction in AC current capacity offset by equivalent DC performance.

Parameter Comparison

Engineering Selection Recommendations

Both the APEM 5664MTHAB and C&K 7411TZQE are active production parts with ROHS3 compliance, ensuring regulatory alignment for current applications. The APEM 5664MTHAB provides superior AC current capacity (6A versus 5A) and extended low-temperature operation (-40°C versus -30°C minimum). The C&K 7411TZQE offers higher electrical life rating (40,000 cycles versus 30,000 cycles), beneficial for high-cycle applications.

Panel cutout diameter differs slightly (12.50mm versus 11.91mm), requiring verification of existing panel hole dimensions before substitution. The actuator length variance (17.50mm versus 17.45mm) is negligible for functional compatibility.

Selection between these parts should be based on application-specific requirements: prioritize the APEM 5664MTHAB for high AC current demands or extended cold-temperature operation; prioritize the C&K 7411TZQE for applications requiring extended electrical life cycles or where panel cutout dimensions accommodate the smaller diameter.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7411TZQE directly replace the APEM 5664MTHAB in existing designs?

A: Direct replacement is possible if the application current requirements do not exceed 5A AC at 120V and the operating temperature range remains above -30°C. Panel cutout diameter must be verified; the C&K part requires an 11.91mm diameter hole versus the APEM part's 12.50mm diameter. If the existing panel hole is sized for 12.50mm, mechanical modification or panel rework is necessary.

Q: What are the key differences in electrical performance?

A: The APEM 5664MTHAB is rated for 6A AC at 125V, while the C&K 7411TZQE is rated for 5A AC at 120V. For DC applications, both support 4A-5A at comparable voltages (30V versus 28V). Applications operating near maximum AC current specifications should retain the APEM part to maintain design margin.

Q: Are both parts suitable for the same environmental conditions?

A: The APEM 5664MTHAB operates from -40°C to 85°C, while the C&K 7411TZQE operates from -30°C to 85°C. Applications requiring operation below -30°C must use the APEM part. Both parts are suitable for standard industrial temperature ranges.

Q: How do the electrical life ratings compare?

A: The C&K 7411TZQE provides 40,000 electrical cycles compared to the APEM 5664MTHAB's 30,000 cycles. For applications with frequent switching operations, the C&K part offers extended service life between maintenance intervals.

Q: What packaging and inventory considerations apply?

A: Both parts are supplied in bulk packaging. The APEM 5664MTHAB has 1051 units in stock, while the C&K 7411TZQE has 933 units in stock. Availability should be confirmed for production quantities and lead time requirements.
